If you could be a Water, Air, Fire or Earth Bender, which one?

Water hands down, in the end water prevails, no amount of fire can flash boil and evaporate the copious amounts of water on and around mother earth. You have the world by the short and curlies, you can dissolve earth, you can extinguish fire, and from an aquatic stand point you can access parts unknown to mankind, go places no man has ever gone before merely part the ocean and walk or ride a wave through the passage there by negating barotrauma.
